Which is greater 6Pr or 6Cr?

Answer 1

6Pr is greater, because there are more arrangements of the data. Because order is important, there are more orders of the data. For instance, if there were 3 objects taken 2 at a time, then the equation for permutations is 3!/(3-2)!=6, while the equations for combinations would be 3!/(3-2)!*3!=1. As you can see, there would be 5 more permutations than there would be combinations.
